Red & black wires go to12 volt as constant. Possibly powered at your radio or cigarette lighter constant 12 volt source. Tue orange and black wires coming out of thw LoJack initially have a white connector which should be attached to a small 12volt back up battery. For in the event that the main power source gets disconnected it will still have power.
The parasitic draw is coming from the Dead back up battery. It is attached to the orange and black wire simply unplug it and buy a new battery or don’t. LoJack will still work only that if vehicle were to be stolen and battery were to be be disconnected it will not work until main battery power is restored.
